uLAT:lNG ASSEPqBI.~ FOR WINDt~W t:)PENINGS
BACKGlROUND OF T~E I~VENTION 1, The present invention r~lates to insulating struc-tures that are adapted to be inserted in a st~ndard window opening on the interior of a room in which the window opening is situated so as to prevent thermal exchange between the internal environment of the room and the external environment. Thus, thermal exchange is minimized both during cold months, when it is desirable to prevent heat loss from the room~, and in the summer; when it is desirable to maintain the room at an inside temperature that is cooler than the outside temperature. The present invention may be employed in conjunction with many existing wind~w structures without interfering with opera-tion of those structures and which may be readily moved between an operative position in the window opening and a stored position away from the window opening.
In the last few years there has been an increasing interest in energy conservation, particularly in the area of home heating and coolingO Studies resulting from this increased interest indicate that, for a typical home, a majority of unwanted energy transfer occurs through the windows and their associated window openings. Such los~es result both from air leakage around the window and from the relatively poor insulating qualities of the thin layer of glass material used in the window 6tructure. Ac-cordingly, by insulating of a window opening, a largeportion of these thermal losses may be eliminated, thus producing substan ial energy savings for the home owner.
The value of insulating a window openiny has ~een recognized for some time, although prior art aktempts at solvin~ this pro~lem have taken different approaches than that contemplated by the present invention. One example of the prior art is the use of windows where an inner and outer panes of glass are separated by a vacuum. Other attempts have included the development of storm windows which comprise several spaced-apart layers of glass having a dead air space there~etween.
Honeycomb blinds having side seals have al50 ~een utilized to create isolated air pockets that thermally insulate the window opening.
Despite the relative successes of these approac~es, there remains a need for a simple yet effective insulating closure for a window opening which closure may be mounted in the room interiorly of the standard window glass. There is a further need for such an insulating cover that is relatively inexpensive to manufacture, pleasing in appearance and which does not require special manufacturing machines. The present invention is directed towards satisfying these remaining needs.

DETAILED DESCRIPTION OF THE REFER~E~ _MBO_IMENT
The present invention relates to window coverinys in the form of an insulating assembly that is adapted to be insertèd into a window opening in order to prevent thermal transmission therethrough. Thus, the present invention is very useful in preventing unwanted heat entry when it is desired to keep the room cooler than the external environment and also to prevent unwanted heat loss when it is desired to keep the room at a temperature greater than the external environment. This invention is further directed to providing a thermal insulating in an inexpensive manner yet in a way that is aesthetically pleasing.
As can be seen in Fiyure 1-4, window assembly 10 is shown mounted in a window opening 12 that is formed in a wall 14 of a building or other structure. A

ceiling 16 extends perpendicularly to wall 14 above window opening 12. Window opening 12 mounts a st~ndard window asse~l~ly 1~ generally towards the exterior of wall 14. On the interior of wall 14, window opening 12 is surrounded ~y a 5a - , : :. : . : .
~ . , - . . , , ~ , , '. ~ . ` :` ' ~' ,,, ` ` ~ " ' , ~q'~
window frame including a lower sill 22, a pair of si~e jambs 24, and an upper sill 26.
Window insulator assembly 10, in the preferred embodiment, is formed of firs~ and second flat panels such as upper panel 28 and lower panel 30 which may be placed in a planar relationship to one another, as is shown in Figure 1, an~ inserted in~o window opening 12. Panels 28 and 30 are sized for close i~ting insertion to opening 12 and thus are configured in the general shape of opening 12. In the figures, this configuration is described with respect to a standard rectangular frame window opening, although the presen~ invention could be employed with other shapes of window openings.
Panel 28 has an upper edge 32 that is pivotally attache~ by hinges 34 to the lower surface of upper sill 26. These hinges allow panel 28 to be piv~ted into the interior of the room so that a lower edge 36 of upper panel 28 may be moved out of opening 12 to a positio~
adjacent ceiling 16, as is shown in phantom in Figure 2.
An upper edge 38 of panel 30 is pivo~ally attached to lower edge 36 by means of hinges 40 so~that panel 30 may be folded back along~ide panel 28 with a lower edge 42 of panèl 30 is alongside edge 32. As i~ shown in Figures 1 and 2, panels 28 and 30 have a common width and thickness, but lower panel 30 is preferably sized to have a longer length than upper panel 28 so that, when panel 30 is folded back alongside panel ~8, ed~e 42 extends into opening 12 past edge 32 of panel 2B. In this manner, panel 30 masks hinges 34 so as to present a more pleasing appearance.
I~ should thu~ be appreciated ~hat window assembly 10 may be moved between an operative posi~ion wherein panels 28 and 30 are substantially planar and inserted in opening 12, as is shown in Figure 2, to a stored position wherein panel 28 is pivoted ~oward ceiling 16 and panel 30 is folded back alongside panel 28. To retain panel 28 in the stored position, a latch mechanism interconnects panel 28~
along its lower edge 36, to a complimentary latch mechanism positioned on ceiling 16~ As is shown in Figures 1 and 2, panel 28 includes a catch 44 located at its interior surface and centered along edge 36. Ceiling 16 is provided with a latch 46 ~hat releaseably engages catch 44. Latch 4~ inclu~es a release lever 48 that, when operated, releases catch 44 after it has been engaged by latch mechanism 46. Latch 46 may typically be of a type commonly used with storm doors and the like, wherein a release lever 48 is depressed to release a ca~ch received by latch 46. A fastener 50 is secured to lower panel 30 along a central portion of its upper edge 38 with fastener 50 also being constructed to engage catch 44 so as to releaseably retain panels 28 and 30 in a planar orienta-tion with respect to one another. A handle 52 is alsomounted on the interior surface of panel 30 along lower edge 42 to facilitate insertion and removal of window insulator assembly 10 into and out of opening ~ 2.
Once upper panel 28 is receive~ by latch 46, it i~
necessary that lower panel ~0 be folded alongside panel 28 so as to prevent lower panel 30 from being an unwanted obstacle depending from ceiling 16, as is shown in Figure 2. As noted above, panel 30 is pivotal on edge 38 and about adjacent edge 36 so that it may be placed in a 30 folded condition. ~ro facilit~te this, a draw cord mechanism is provided. Specifically, a mounting member 54 is attached to the outer surf~ce of lower panel 30, adja-cent edge 42. ~ re~aining pulley 56 is mounted at an upper corner of opening 12, with pulley 56 being attached, by any convenient bracket, to upper sill 26~ Retaining pulley 56 is of a type c~mmonly used with venetian blinds that permits selective adjustment and gripping of a cord threaded therethrough. To this end, a cord 66 is fastened, at one end, to mounting member 54 and is threaded through pulley 56 so that cord 66 has a free end 68 that hangs alongside one of side jambs 24 in opening 12. By pulling on free end 68 of cord 66, edge 42 of panel 30 is drawn toward edge 32 of panel 28 so that panels 28 and 30 are placed in a folded configuration, as is shown in phantom in Figure 2.
In order to facilitate a complete seal around and between panels 28 and 30, edge seals, upper and lower seals, and an intermediate seal are provided. Specifical-ly, as is shown in Figure 1, an upper seal 70, in the form of a strip of compressible material, extends across the entire width of panel 28 on edge 32, and an intermediate seal 72 is mounted on one of facing edges 36 and 38 com-pletely across the common width of panels 28 and 30. when panels 28 and 30 are placed in a planar position, edges 36 and 38 compres~ seal 72 prevent air from passing between these adjacent edges of panels 28 and 30. Likewise, when panel 2B is placed in a nested position within opening 12, seal 70 i5 pivoted against top sill 26 to prevent air from passing across the top of panel 28. To complete .the sealing of the perimeter of panels 28 and 30~ side ribs 74 are attached to side jambs 24 and side seals 76, in the form of elongated, compres~ible strips extend along side edges of each of panels 28 and 30, and include end 3~
portions 77 that overlap respective edges 32, 36, 38 and 42. A bottom rib 78 extends across lower seal 22 in a common plane with side ribs 74. Rib 78 has an outwardly facing surface that receives an elongated, compressible sealing strip 80. When panels 28 and 30 are in a planar position and are inserted into close-fitting engagement with opening 12, the side seals 76 compress against ribs 74 and a lower edge portion o~ lower panel 30 abuts and compresses sealing strip 80 so that, in conjunction with upper strip 70, completely seals the perimeter of this panel assembly. Instead of placing seals 76 on panels 28 and 30, seals 76 could be directly mounted to ribs 74 in a manner similar to that described for seal 80.
Panels 28 and 30 may be formed of any convenient material, but, in the preferred form of this invention, a light-weight, polystyrene foam material is selected, The front and back surfaces of each of panels 28 and 30 are provided with a stiffening or backing material 82, shown with respect to panel 30 in Figure 4, which may be in the form of a light-weight cardboard, that helps strengthen polystyrene foam panels 28 and 30 from accidental breakage yet which maintains their lightweight construction. To further strengthen panels 28 and 30, as is shown in Figure 1 and 4, each of panels 28 and 30 include a channel-shaped molding that extends completely around their re3pective perimeters. These molding3 ma~ be formed of a wood or plast;c material, but it is preferred that each of molding pieces 84 be i~ .

formed of a non-thermally conducting substance.
Further, to enhance the appearance of panels 28 and 30 from the interior of the room in which window opening 12 is formed, a decorative material 86, such as a 9a .. . . . ~ ~ ~ .

The operation of window insulator assembly 10 can now be more fully appreciated and understood. When it is desired to move insula~ing assembly 10 out of an insula-ting relationship wi~h opening 12, fastener 50 is ro~ated so ~hat it releases ca~ch 44, and the user pulls handle 52 so as to remove panels 28 and 30 from opening 12. This movement pivots panel 28 about ~op sill 26 on hinges 34 so that edge 36 moves toward ceiling 16. Simultaneously, panel 30 is maintained in a vertical orientation, as is shown at A in Figure 2, so that panels 2~ and 30 pivot L5 with respect to one another. This movement is continued until catch 44 engages latch 46 and is retained thereby.
~andle 52 may then be released and the user may pull free end 68 of c~rd 66 so that edge 42 is drawn toward edge 32 and is retained in the folded position shown at B in ~ Figuxe 2, by manipulating retaining pulley 56 as is known in the art. When it is desired to release panels 28 and 30 rom the folded or &tored position, free ~nd 68 is again manipulated to release cord 66 from retaining pulley 62 so that panel 30 is again moved generally perpendicular to a vertical po~ition perpendicular to ceiling lfi. In order to release panel 28, the user pulls handle ~2 out-wardly away from wall 14 so that edge 38 of panel 30 attacks release lever 48, as is ~hown in Figure 2, so that, when lever 48 is moved a ~ufficient distance, latch 46 releases catch 44. Panels 28 and 30 are then pivoted with respect to one another while panel 28 is pivoted on hinges 34 so that the panels move into abutment with ribs ~O
74 ~nd 78. Thi~ compresses upper seal 70, intermediate seal 72, side seals 76 and bottom seal 80 so that a rela-tively air~tight structure is provided.
From the foregoing, it should be appreciated that latch 46 and retaining handle 48 must be positioned so that edge 38 may attack release lever 48. To ~his end, as is shown in Figure 2, latch 46 is mounted on a block 88 that has an inclined sur~ace 90 that is formed at an angle with respect to ceiling 16 which is approximately the same as the angle panel 28 makes with ceiling 16 when catch 44 is received by latch 46;- To permit edge 38 to more con-veniently at~ack release lever 48, a spacer ~lock 92 may be mounted on release lever 48. Spacer block 92 has an inclined surface 94 that is generally parallel ~o ceiling 16 and is sized so that edge 38 will attack inclined surface 94 upon only a relatively small outward movement of panel 30 outwardly into the room. To further enhance this structure, upper edge 32 of panel 38 may be attached to upper sill 26 by means of a mounting member 96t such as a flat board, which extends across top sill 26 and is attached the~eto. Hinges 34 and pulley 56 are then at-tached to mounting member 96. In this manner, window insulator assembly 10, with the exception of side ribs 74 and bottom rib 78 may be completely removed from opening 12 simply by removing mounting member 96.
Accordingly, the present invention has been described with some degree of particularity directed to the pre-ferred embodiment of the present invention. It should be apprec.iated, though, that the present invention is d~fined by the following claims construed in light of the prior art so ~hat modif ica~ion~ or changes may be made to the preferred embodiment of the present invention without ¦, departing from the inventive concepts contained herein.

ceiling 16 extends perpendicularly to wall 14 above window opening 12. Window opening 12 mounts a st~ndard window asse~l~ly 1~ generally towards the exterior of wall 14. On the interior of wall 14, window opening 12 is surrounded ~y a 5a - , : :. : . : .
~ . , - . . , , ~ , , '. ~ . ` :` ' ~' ,,, ` ` ~ " ' , ~q'~
window frame including a lower sill 22, a pair of si~e jambs 24, and an upper sill 26.
Window insulator assembly 10, in the preferred embodiment, is formed of firs~ and second flat panels such as upper panel 28 and lower panel 30 which may be placed in a planar relationship to one another, as is shown in Figure 1, an~ inserted in~o window opening 12. Panels 28 and 30 are sized for close i~ting insertion to opening 12 and thus are configured in the general shape of opening 12. In the figures, this configuration is described with respect to a standard rectangular frame window opening, although the presen~ invention could be employed with other shapes of window openings.
Panel 28 has an upper edge 32 that is pivotally attache~ by hinges 34 to the lower surface of upper sill 26. These hinges allow panel 28 to be piv~ted into the interior of the room so that a lower edge 36 of upper panel 28 may be moved out of opening 12 to a positio~
adjacent ceiling 16, as is shown in phantom in Figure 2.
An upper edge 38 of panel 30 is pivo~ally attached to lower edge 36 by means of hinges 40 so~that panel 30 may be folded back along~ide panel 28 with a lower edge 42 of panèl 30 is alongside edge 32. As i~ shown in Figures 1 and 2, panels 28 and 30 have a common width and thickness, but lower panel 30 is preferably sized to have a longer length than upper panel 28 so that, when panel 30 is folded back alongside panel ~8, ed~e 42 extends into opening 12 past edge 32 of panel 2B. In this manner, panel 30 masks hinges 34 so as to present a more pleasing appearance.
I~ should thu~ be appreciated ~hat window assembly 10 may be moved between an operative posi~ion wherein panels 28 and 30 are substantially planar and inserted in opening 12, as is shown in Figure 2, to a stored position wherein panel 28 is pivoted ~oward ceiling 16 and panel 30 is folded back alongside panel 28. To retain panel 28 in the stored position, a latch mechanism interconnects panel 28~
along its lower edge 36, to a complimentary latch mechanism positioned on ceiling 16~ As is shown in Figures 1 and 2, panel 28 includes a catch 44 located at its interior surface and centered along edge 36. Ceiling 16 is provided with a latch 46 ~hat releaseably engages catch 44. Latch 4~ inclu~es a release lever 48 that, when operated, releases catch 44 after it has been engaged by latch mechanism 46. Latch 46 may typically be of a type commonly used with storm doors and the like, wherein a release lever 48 is depressed to release a ca~ch received by latch 46. A fastener 50 is secured to lower panel 30 along a central portion of its upper edge 38 with fastener 50 also being constructed to engage catch 44 so as to releaseably retain panels 28 and 30 in a planar orienta-tion with respect to one another. A handle 52 is alsomounted on the interior surface of panel 30 along lower edge 42 to facilitate insertion and removal of window insulator assembly 10 into and out of opening ~ 2.
Once upper panel 28 is receive~ by latch 46, it i~
necessary that lower panel ~0 be folded alongside panel 28 so as to prevent lower panel 30 from being an unwanted obstacle depending from ceiling 16, as is shown in Figure 2. As noted above, panel 30 is pivotal on edge 38 and about adjacent edge 36 so that it may be placed in a 30 folded condition. ~ro facilit~te this, a draw cord mechanism is provided. Specifically, a mounting member 54 is attached to the outer surf~ce of lower panel 30, adja-cent edge 42. ~ re~aining pulley 56 is mounted at an upper corner of opening 12, with pulley 56 being attached, by any convenient bracket, to upper sill 26~ Retaining pulley 56 is of a type c~mmonly used with venetian blinds that permits selective adjustment and gripping of a cord threaded therethrough. To this end, a cord 66 is fastened, at one end, to mounting member 54 and is threaded through pulley 56 so that cord 66 has a free end 68 that hangs alongside one of side jambs 24 in opening 12. By pulling on free end 68 of cord 66, edge 42 of panel 30 is drawn toward edge 32 of panel 28 so that panels 28 and 30 are placed in a folded configuration, as is shown in phantom in Figure 2.
In order to facilitate a complete seal around and between panels 28 and 30, edge seals, upper and lower seals, and an intermediate seal are provided. Specifical-ly, as is shown in Figure 1, an upper seal 70, in the form of a strip of compressible material, extends across the entire width of panel 28 on edge 32, and an intermediate seal 72 is mounted on one of facing edges 36 and 38 com-pletely across the common width of panels 28 and 30. when panels 28 and 30 are placed in a planar position, edges 36 and 38 compres~ seal 72 prevent air from passing between these adjacent edges of panels 28 and 30. Likewise, when panel 2B is placed in a nested position within opening 12, seal 70 i5 pivoted against top sill 26 to prevent air from passing across the top of panel 28. To complete .the sealing of the perimeter of panels 28 and 30~ side ribs 74 are attached to side jambs 24 and side seals 76, in the form of elongated, compres~ible strips extend along side edges of each of panels 28 and 30, and include end 3~
portions 77 that overlap respective edges 32, 36, 38 and 42. A bottom rib 78 extends across lower seal 22 in a common plane with side ribs 74. Rib 78 has an outwardly facing surface that receives an elongated, compressible sealing strip 80. When panels 28 and 30 are in a planar position and are inserted into close-fitting engagement with opening 12, the side seals 76 compress against ribs 74 and a lower edge portion o~ lower panel 30 abuts and compresses sealing strip 80 so that, in conjunction with upper strip 70, completely seals the perimeter of this panel assembly. Instead of placing seals 76 on panels 28 and 30, seals 76 could be directly mounted to ribs 74 in a manner similar to that described for seal 80.
Panels 28 and 30 may be formed of any convenient material, but, in the preferred form of this invention, a light-weight, polystyrene foam material is selected, The front and back surfaces of each of panels 28 and 30 are provided with a stiffening or backing material 82, shown with respect to panel 30 in Figure 4, which may be in the form of a light-weight cardboard, that helps strengthen polystyrene foam panels 28 and 30 from accidental breakage yet which maintains their lightweight construction. To further strengthen panels 28 and 30, as is shown in Figure 1 and 4, each of panels 28 and 30 include a channel-shaped molding that extends completely around their re3pective perimeters. These molding3 ma~ be formed of a wood or plast;c material, but it is preferred that each of molding pieces 84 be i~ .

The operation of window insulator assembly 10 can now be more fully appreciated and understood. When it is desired to move insula~ing assembly 10 out of an insula-ting relationship wi~h opening 12, fastener 50 is ro~ated so ~hat it releases ca~ch 44, and the user pulls handle 52 so as to remove panels 28 and 30 from opening 12. This movement pivots panel 28 about ~op sill 26 on hinges 34 so that edge 36 moves toward ceiling 16. Simultaneously, panel 30 is maintained in a vertical orientation, as is shown at A in Figure 2, so that panels 2~ and 30 pivot L5 with respect to one another. This movement is continued until catch 44 engages latch 46 and is retained thereby.
~andle 52 may then be released and the user may pull free end 68 of c~rd 66 so that edge 42 is drawn toward edge 32 and is retained in the folded position shown at B in ~ Figuxe 2, by manipulating retaining pulley 56 as is known in the art. When it is desired to release panels 28 and 30 rom the folded or &tored position, free ~nd 68 is again manipulated to release cord 66 from retaining pulley 62 so that panel 30 is again moved generally perpendicular to a vertical po~ition perpendicular to ceiling lfi. In order to release panel 28, the user pulls handle ~2 out-wardly away from wall 14 so that edge 38 of panel 30 attacks release lever 48, as is ~hown in Figure 2, so that, when lever 48 is moved a ~ufficient distance, latch 46 releases catch 44. Panels 28 and 30 are then pivoted with respect to one another while panel 28 is pivoted on hinges 34 so that the panels move into abutment with ribs ~O
74 ~nd 78. Thi~ compresses upper seal 70, intermediate seal 72, side seals 76 and bottom seal 80 so that a rela-tively air~tight structure is provided.
From the foregoing, it should be appreciated that latch 46 and retaining handle 48 must be positioned so that edge 38 may attack release lever 48. To ~his end, as is shown in Figure 2, latch 46 is mounted on a block 88 that has an inclined sur~ace 90 that is formed at an angle with respect to ceiling 16 which is approximately the same as the angle panel 28 makes with ceiling 16 when catch 44 is received by latch 46;- To permit edge 38 to more con-veniently at~ack release lever 48, a spacer ~lock 92 may be mounted on release lever 48. Spacer block 92 has an inclined surface 94 that is generally parallel ~o ceiling 16 and is sized so that edge 38 will attack inclined surface 94 upon only a relatively small outward movement of panel 30 outwardly into the room. To further enhance this structure, upper edge 32 of panel 38 may be attached to upper sill 26 by means of a mounting member 96t such as a flat board, which extends across top sill 26 and is attached the~eto. Hinges 34 and pulley 56 are then at-tached to mounting member 96. In this manner, window insulator assembly 10, with the exception of side ribs 74 and bottom rib 78 may be completely removed from opening 12 simply by removing mounting member 96.
Accordingly, the present invention has been described with some degree of particularity directed to the pre-ferred embodiment of the present invention. It should be apprec.iated, though, that the present invention is d~fined by the following claims construed in light of the prior art so ~hat modif ica~ion~ or changes may be made to the preferred embodiment of the present invention without ¦, departing from the inventive concepts contained herein.
